This function describes the manual procedure of self learning "iTPMS".
The vehicle may be equipped with the "iTPMS" (indirect tire pressure monitoring system) which monitors the tire inflation status using the wheel speed sensors. The "iTPMS" is controlled by the ESC control unit (electronic stability control), which uses the wheel speed sensors and a complex calculation algorithm to detect different tire rolling speeds, and then assume that there has been a change in its perimeter and signalling its deflation. The system warns the driver if one or more tires are flat by lighting up the warning light continuously and a warning message is displayed. If one tire only is flat, the system can indicate its position, it is recommended to check the pressure on all four tires.
The system is active for speeds above 15 km/h. In a few situations (such as sporty driving, winter climate or gravel roads) the wheel signal may be delayed. Under special conditions (e.g. vehicle loaded asymmetrically on one side, towing a trailer, damaged or worn tires, fitting the spare wheel, fitting snow chains, fitting different tires on the axles) the system may give false indications or be temporarily deactivated. If the system is temporarily deactivated, the warning light flashes for about 75 seconds and then is continuously on, at the same time, the display shows the message "TYRE PRESSURE MONITORING NOT AVAILABLE". This indication will also appear after the ignition has been switched off and then on again, if the correct operating conditions are not restored.
"iTPMS" needs an initial self-learning phase (whose length depends on the driving style and road conditions) which starts when the reset procedure is performed.
Ezt a funkciót akkor kell elvégezni, ha:
Abroncsnyomás megváltoztatása után.
Ha kicserélt egy vagy több gumiabroncsot.
If one or more wheels has changed the rotational direction.
If the spare wheel has been mounted.
Before performing the reset, inflate the tíres to the specified pressure values. If the reset is not performed, in all above cases, the warning light may give false indications on one or more tires.
Gyújtás bekapcsolva, motor kikapcsolva.
Press the iTPMS SET (reset) button for 2 seconds, see picture.
After completed reset, the display shows the message "RESET SAVED", as an indication that the self learning has started.
